In today's interconnected digital landscape, ensuring secure communication between SAP systems and their components is paramount. With growing threats of cyberattacks, data breaches, and regulatory compliance requirements such as GDPR, secure network communication becomes a foundational pillar in SAP Security Operations. This article outlines the importance, methods, and best practices for implementing secure communication within SAP environments.
SAP systems are often the backbone of enterprise operations, handling sensitive business data including financial records, personal employee information, and proprietary business processes. Unencrypted communication can expose this data to:
To mitigate these risks, implementing end-to-end encryption, authentication, and integrity checks is critical.
SNC is the standard SAP mechanism to ensure encrypted, authenticated, and secure communications between SAP GUI clients and SAP application servers. It relies on external security libraries like SAP Cryptographic Library or partner solutions such as Microsoft Kerberos or SSO tools.
Features of SNC:
SSL/TLS is used to secure communication over HTTPS between browsers and SAP NetWeaver services (e.g., ICM, Web Dispatcher). It also secures communication between SAP systems via web services or RFC over HTTP.
Applications:
SAProuter is an SAP proxy that controls traffic between internal and external networks. When configured with SNC or TLS, it ensures secure routing of messages across firewalls and DMZs.

SAP Security Operations teams must ensure that SNC, SSL/TLS, and SAProuter are correctly configured and maintained to protect business data, comply with legal regulations, and build stakeholder trust. With evolving threats, ongoing vigilance and updates to the security infrastructure are essential.
